This invention relates to jewelry hinges and more particularly to hingesfor brooches, lockets, pendants and the like.

Among the principal objects of the invention are the provision of ahinge for articles of jewelry such as aforesaid which is sturdy, silentin operation and simple to construct. In the accompanying drawings inwhich I have illustrated a preferred embodiment of my invention ap liedto a brooch:

Figure 1 is a ront elevation; Fig. 2 is a rear elevation; Fig. 3 is anend elevation of the brooch with the hinged watch carried thereby shownin an open position;

h Fig. 4 is a longitudinal elevation of the inge;

Fig. 5.is a vertical section on the line 5-5 of Fig. 4; Fig. 6 is anelevation with the smaller half of said hingecylinder removed; I

Fig. 7 is an elevation of the smaller half of the hinge cylinder;

Fig. 8 is a vertical sect-ion on the line 88 of Fig. 6; and I Fig.9'is-a fragmentary end view of the hinge cylinder showing the pintle insection.

Referring to the drawings and the construction shown therein thereference numeral 1 designates a loop-shaped or approximatelyrectangular frame or rim of a brooch to which is movably secured ahollow casing 2, adapted to serve as. a mounting for a watch 3. A pin 4serves to fasten said brooch to a garment or the like. Said frameterminates in shoul-' dersor flanges 5 between which is rigidly anchoreda pintle 6. Stop segments 7 are secured to the faces of said flanges 5,which segments serve to limit the movement of the 40 hinged casin '2when the same is moved to observe the ace of the watch that is normallyconcealed from view.

The hinge proper comprises two semi-cylin; drical members or sections 8and 8' respectivel the latter being a trifle shorter than the ormer, sothat when the two are assembled, one straight edge of each stop 7 willengage the edges A of the member 8 when the casing 2 is in the' positionshown in Fig.

' 1 and the other straight edge of each stop will engage the edges Bwhen said casing is one of said knuckles and a torsion spring 13.

which encircles the pintle 6 has one of its ends inserted throughsaideye 12 and its other end inserted through a hole 14 in pintle 6,both ends being upset to prevent escape from their anchorages.

The stem 15 of the watch carried by the casing '2 is normally pressedinto engagement with the groove 16 formed in the frame 1 by the actionof the said torsion spring. The latter is of just suflicient tension toeasily return the watch from the position shown in Fig. 3 when thepressure exerted thereon is released, but admits of said watch beingreadily moved into the position shown in Fig. 3 when it is desired toobserve the time therefrom. Furthermore, the tension of the spring issuch that the amount of pressure required to move the watch from'itsclosed to its open position isnot noticeably accelerated'as the watch isbeing moved into its open position.

The assembly of the brooch is simple and requires but little time andthe hinge thereof instead of detracting from the appearance isunobstrus'ive and-adds to the symmetry of the article.

While I have illustrated an article of jewelry in which the hinge isvisible from the front, I may, for the sake of appearances and withoutdeparting from the spirit of'my invention, conceal the cylinder byextending the frame on the front as an enveloping hemicylindrical shellconcentric with said cylinder and integral with the frame or solderedthereto.

-Various modifications within the scope of the appended claims may bemade without dearting from the spirit of my invention as herein setforth.

Having thus described myv invention what I I claim and desire to obtainby United States Letters Patent is 1. In an article of jewelry thecombination comprising a split frame having opposing terminal flanges,an axle rigidly secured thereto between said flanges, stop segmentsprojecting from the outer faces of said flanges, said segments lyingwithin the periphery of said flanges, a sectional cylindrical m casingmounted on said axle, said casing comprising two hemi-oylindricalmembers,"said assembled cylinder having semi-circular terminal stopsegments adapted'to co-operate with the aforesaid stops on said flangesand a torsion spring enveloping said axle and secured by its respectiveends to said axle and said cylinder and adapted to normally hold thelatter in a predetermined position.

2. In a brooch, the combination compris- 2o ing a skeleton frame, havingopposing transversely projecting flanges interconnected by a reducedneck portion adapted to serve as an axle, a stop lug projectinglongitudinally" of said frame from at least one of said flanges, andlying within the periphery of the flange from which it projects, asectional cylinder comprising two semi-cylindrical members one of whichis slightly shorter than the other, thereby forming at least onesemi-circular 3o terminal stop adapted to cooperate with the aforesaidstop and limit the extent of movement of said cylinder in each-directionof rotation thereof and a spring adapted to normally hold said cylinderin a predetermined position and to return the cylinder to such positionwhen externally applied pressure on said cylinder is released.

3. In an article of jewelry, the combination comprising a skeleton framehaving spaced 40 parallel flanges interconnected by. an axle member, acylindrical casing rotatably mounted on said axle, said casingcomprising two hemi-cylindrical members, one of which is shorter thanthe other, thereby affording at least one terminal lug member, a stopcarried by said frame adapted to cooperate'with said lug to limit theextent of rotation of the cylindrical casein both directions and elasticmeans for normally holding said cylinder in a predetermined'position andfor returning said cylinder to such position when externally appliedpressure on said cylinder is released.- Signed at New York, m the countyand State of New York, this 7th day of'Ma-rch,
